3.Product feature

♦ Indoor installation.

♦ The ambient temperature is not higher than +40 °C, not less than -5 °C, and 24hs average temperature does not exceed the +35 °C.

♦ Air cleaner, the relative humidity at the highest ambient temperature of +40 °C not more than 50% in the lower temperature allows a higher humidity, as in +20 °C, relative humidity of 90%, and allow accidental temperature changes a small amount of condensation produced

♦ altitude does not exceed 2000m.

♦ Pollution degree: 3.

♦ during transportation and storage temperature of -25 °C~ +55 °C, in a short time (less than 24h) up to +70 °C.

♦ device used in some of the electrical components and accessories do not meet these conditions and conditions of use does not match with the normal conditions, by the manufacturer and user consultation.
